[Lubuntu] Evaluation of presentation programs?

[John Hupp]

I know about LibreOffice Impress as a mature product.  I have read a 
little about Ease (very new and rather rough at last report, not in the 
main repos, requires 3D support by the video driver and therefore often 
the proprietary video driver).

What are my best options for a presentations program that is:
- very solid and reliable
- well documented
- can produce presentations in a format that can be viewed by people who 
only have PowerPoint
- and /preferably/ is also light without a ton of dependencies
